Rose plant

ABSTRACT

A miniature rose variety having a well branched, upright plant; orange-colored buds turning to light pink flowers; little or no fragrance.

This present invention relates to a new and distinct variety of roseplant of the miniature class which was originated by me by crossing anunnamed variety, which itself was a cross between the variety Bangor andthe variety Anabell (otherwise known as Korbell), with the pollen of thevariety Nozomi.

The primary objective of this breeding was to produce a new miniaturerose variety of upright habit, compact growth, and clean foliage withbuds and blooms of an orange color. This objective was substantiallyachieved along with other desirable improvements as evidenced by thefollowing unique combination of characteristics which are outstanding inthe new variety and which distinguish it from its parents as well asfrom all other varieties of which I am aware:

1. Well branched, upright plant reaching less than 24" after one year'sgrowth.

2. Orange colored buds turning to light pink in the aged open flowers.

3. Strong resistance to rose powdery mildew.

4. Few thorns.

5. Little or no fragrance.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing characteristics and distinctionscome true to form and are established and transmitted through succeedingpropagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor in terminology in accordance with The Royal Horticultural SocietyColour Chart except where ordinary dictionary significance of color isindicated.

I claim:
 1. A new and distinct variety of rose plant of the miniatureclass, substantially as herein shown and described, characterizedparticularly as to novelty by the unique combination of its heavilybranched, upright miniature plant bearing orange colored buds opening topink mature flowers with no fragrance, and its resistance to rosepowdery mildew.
